The GRIB files can also contain data related to the 500mb charts. A 500mb fax would typically look like this:It is really supposed to represent the topography of the atmosphere...Other rendering(s) of the same data might be helpful, like this one:Plus it is really animated, you can orient it the way you want, just with the mouse.The four lows are really easy to spot, notice that the one in the Gulf of Alaska is not that impressive, and look - it is not on the fax, it's beyond its edge - how much fun they're going to have in the south Japan...Sea temperature and PRMSL (Pressure at Mean Sea Level) can also be represented the same way. I want to check if wave heights can be represented the same way...
